Database Sharing Considerations

To enable the BES primary database and mirror database between multiple BES tasks, consider the following:

• To share the databases between LPARs, they must be allocated on shared DASD.
• Update the parmlib parameters to define the primary database and the mirror database to specify the same values for all systems sharing the databases.
• If any combination of CA Tape Encryption, the Option Application Management, and the Option for IBM are being used, map a single tape management system catalog to a single BES primary database.

  If you use:

  • CA 1, there should be one primary and mirror database for each TMC.
  • CA TLMS, there should be one primary and mirror database for each VMF.
  • DFSMSrmm, there should be one primary and mirror database for each CDS.

  CA Tape Encryption creates a unique key index for each symmetric key it creates. This key index is passed to the tape management system and maintained in the tape management system catalog.

• For each BES task that initializes using this database, the database provides a separate storage area to retain information.
